Application filed =February 26, 1919. Seria1 No. 279 376.

This invention relates to the art of fuel homogenizers, and particularly to a device of this kind adapted especiallyfor use in internal combustion engines and carbureters of automobiles.

The invention in its broadest aspect aims to provide an improved device for mixing the fuel, thereby increasing its combustibility, in order to render each charge more efficient, prior to entering the combustion chamber through the intake manifold.

Further it is the aim to providemeans located between the intake manifold and the carbureter, and being intermittently revoluble under the influence of the fuel or charges, incident to the intake strokes of the piston of the engine, and in which means revoluble screening devices are included, notonly to screen the fuel, but also acting to break or disintegrate the particles, thereby insuring a finer and superior combustible fuel.

The invention further aims to afford an additional revoluble member in advance of the screening devices to further break the particles of the fuel, imparting a fanning. action thereon, which will agitate and thoroughly mix the charge.

The invention further aims to provide supporting means, on which the intermittent revoluble means is supported, there being means afforded, such as cup-shaped agate thrust bearings for the supporting means, whereby the intermittent revoluble means may easily and freely rotate under the influence of the fuel'in its passage through the manifold.

The design of the invention at the present time has been found practical. However, in reducing the inventionto a practical form for commercial purposes, alterations in the minor details may be found necessary, and

the right to these alterations is claimed, pro- I vided they are warranted by what is claimed.

The invention comprises further features and combinations of parts, as will be here inafter set forth, shown in the drawings and claimed.

In the drawings:

, Fig. 2 is a detail view in section of the mixing device removed from the casing, showing the casing of the mixing device in section, and illustrating the supporting means for the mixing elements.

screen member and the retainer therefor and the intermediate bands, and the collars.

Fig. 5 is an enlarged detail view of one of the cup-shaped agate thrust bearings.

Referring to the drawings 1 designates an intake manifold and 2 a portion of a carbureter. The manifold is provided with a cylindrical extension 3 having an annular flange 4 at its lower end. An elbow casing 5 is interposed between the extension 3 and the carburetor, and one end of the elbow casing is supplied with an annular flange 6, through which and the flange 4 suitable bolts having nuts pass, thereby securing the adjacent flanges together, and supporting the elbow caslng in position.

It is to be observed that the elbow casing at a point adjoining its flange 6 is provided. with a depresslon 8. On the interior of the ing 10 firmly in position. It is obvious that when the extension and the elbow casing are separated, the casing 10 maybe inserted in the elbow casing whereby its flange 11 may engage the annular depression 8, after which the elbow casing may be bolted in position, the other end of the casing 10 protruding telescopically into the extension 3. n

Secured by cap screws or thelikc 12 on one end of the casing 10 and transversely thereof are radial arms 13 of'the collar 15,the opening 14 of which is threaded. The other end 70 Fig. 4 illustrates collective views of the The interiors of the shanks of the screws are designed for the reception of cup-shaped agate thrust bearings 21 and 22. In order to retain the bearings in the shanks of the screws, the marginal edge portions, of the shanks are upset as shown at 28, in order to overlie the marginal portion of the bearings. These bearings are also axially alined, and are designed to receive the opposite ends of a shaft 24. constructed of suitable metal, preferably steel. Revolving with the shaft :24 is a sleeve 25, it being obvious that the 2O shaft 24 is capable of free revoluble move ments in its axial bearings. One end of the sleeve is provided with radial fan blades 26 oppositely pitched, so that incident to the influence of the fuel being drawn into the manifold upon the intake stroke of the piston, revoluble movement will be imparted to the shaft, consequently the sleeve.

Formed integral with the other end portion of the sleeve are radial arms 27, integral with which is a. depending cylindrical retaining wall 28. 'This casing 10 is constructed in two'sections, and where its annular flange 11 is formed, the sections are joined. The

V section29 of the casing 10 has its interior larger in diameter than the interior of the section 30. Hence, a shoulder 31 is provided on the interior of the casing 10. By this construction, it is clear that the parts contained in the casing 10 can be easily assembled and arranged in place. The sleeve 25 constitutes a hub for the retainer 28. Arranged in the retainer wall is a plurality of fuel screening me bers 32 arranged in series, These screening members haveannular portions 38, which extend in the same direction and are'concentric. Arranged between thescreemng members are annular bands 34L, thereby holding the screening member spaced, and in position. In order to arrange the screenlng members lILthe retainer they'are provided with central open- ,ings for the reception of the end of the sleeve, which constitutesthe hub of the retainer. Collars 35 are arranged telescopically upon the hub of the retainer, and intermediate the screening members, in order I 'to additionally hold the same spaced, and at r the same time preventing dishing.

*cent the lowermost collar 35, and in order to support the collars a holding collar 36 is fastened to the end of the sleeve.

Adj a- This holding collar 36-isjsu pplied :with' radial arms 37, which areintegrally connected to an annular ring 38, which engages the lowermost band 34, so as to holdthe bandsand the screening since the screening members are also rapidly revolving the fuel or charge is thoroughly mixed and broken up into the finest possible particles, and at the same time is mixed with the proper portion of air. This action insures a superior combustible charge for internal combustion engines, increasing the power and efliciency of the engine and at the same time reducing fuel consumption, thereby cutting down the operating expenses.

The invention having been set forth, what is claimed as new and useful is:

1. In a fuel mixing mechanism, the combination with a freely revoluble shaft, of a sleeve rotatable therewith, a mixing mecha nism retainer depending from the sleeve, the end of the sleeve opposite the retainer being provided with blades, fuel mixing means in the retainer, and a casing for the aforesaid parts, provided with bearings for the shaft, said mixing means comprising a plurality of spaced screening elements having annular portions, spacing bands therefor, engaging the annular portions of the screening elements, collars on the sleeve additionally spacing the screening elements and preventing them from dishing, and means for clamping the parts of the mixing mechanism in posltion.

2.-In a device for mixing fuel, the combination with a casing having its opposite ends open, and provided with axially alined supporting bearings, of a shaft revoluble in said bearings, a sleeve rotatable therewith, the upper end of the sleeve having blades, the lower portion of the sleeve having a depending retainer open at both ends, one end of the retainer having radial arms, a plurality of screen members having annular portions, super-imposed and spaced, bands telescoping within the annular portions of the screen members, collars mounted on the sleeve between the screen members preventing dishing of the screen members, and

7 means on the lower end of the sleeve for depending from said arms, a supporting device detachably carried on the lower end of the sleeve, a plurality ofiuel mixing elements super-imposed and spaced and interposed between the arms and the supporting device at the lower end of the sleeve, said mixing elements having annular portions, means engaging within said elements and clamping their annular portions in contact with the wall of the retainer, means on the sleeve interposed between said elements for holding the central parts of the elements against dishing, and a holder for the revoluble sleeve.

4. In a mixing device, the combination with a revoluble sleeve, of a plurality of fuel mixing elements mounted on the sleeve super-imposed in spaced relation to each other and provided with marginal portions, means engaging within and exteriorly of the portions, to hold the elements spaced, the means eXteriorly of the portions being carried by the sleeve, and means on the lower end of the sleeve for supporting the interior means in position.

5.
